**1. Introduction**

Usually, the concept of financing covers many sources of financing, and banking is one of the sources. Green banking is a new trend of banks' financing. It is a product of green movement initiated by world leaders to maintain a livable condition for future generations [1]. The recent commitments of leaders to attain sustainable development goals (SDGs) by 2030 will be impossible without successful implementation of green banking. It is a new avenue for both conventional and Islamic banks to care for the environment while financing.

Green banking is an eco-friendly financing. Banks' concern about environmental well-being while financing to businesses is considered as green banking. To get a sustainable positive impact from business, green banking is essential. Businesses are the driver of the economy, and sustainable business can influence the sustainability of the economy; therefore, successful green business establishment is crucial. Central banks' role is imperative in introducing and implementing green banking.

Green banking has a positive connection with Maqasid Shariah as well as few of sustainable development goals such as goal no. 7, 9, 11, 12, and 13. On the other hand, green banking features and objectives are very close to Maqasid Shariah. The objective of Shariah (Islamic law) is known as Maqasid Shariah. The term Maqasid refers to purposes or goals in Arabic. Basically, the word Maqasid Shariah refers to the devotions of Islamic law. The purposes, rationales, as well as common good in the Islamic rulings are accentuated by the term Maqasid while basing itself on the Islamic scripts as well as observing the Islamic faith. In general, conservation,

reduced dependency on paper, increased online banking, and environmental risk rating before granting financing to a borrower are few features of green banking which do not contradict with Maqasid Shariah rather meet the objectives of Shariah. This chapter is divided into various sections for easy representation of the detail of green banking: the second section is going to discuss about the methodology used to gather data, the third section explains what is green banking, the fourth section represents the importance of it, the fifth section elaborates the impact of it to introduce green business, the sixth section demonstrates the link among green banking, Islamic banking, Maqasid Shariah, and SDGs, and finally, the conclusion sums up the chapter.
